Genetic counselors on the frontline of precision health.

By enabling precise genetic diagnosis and treatment there is great potential for inexpensive, accurate, and widely accessible genomic information to transform health care and improve the general well-being of virtually every person. To maximize this potential, approaches to genetic counseling and the role of genetic counselors will need to adapt to fit changing clinical and commercial needs worldwide. This will require overcoming multiple challenges including an inadequate workforce; development and implementation of alternate models of service delivery; integration of new technologies to improve, extend, and expand services; and support for equitable education and counseling among all populations. Genetic counselors are aptly poised to take on these challenges. The result will be better informed patients and families more capable of utilizing genetic information appropriately, making autonomous decisions about their care, and modifying their approach to disease risk to actively contribute to their health. The contributors to this issue of Seminars discuss how key areas of genetic counseling need to evolve and how genetic counselors can play a role in shaping the future of precision health.
